EMC Standards

NOTE!
- All EMC specifications are stated with
factory settings.
- Maximum 4 kHz switching frequency.
- Shielded data/control cables must be
used for surge protection.
- The FCM 300 must be connected to
ground in order to comply.
- Maximum/minimum line impedance
Z = 0.24 + j0.15 ohm; Z
max
j0 ohm.
(EN 61800-3 commutation notches)
Generic standards
The generic standards are stated in the EMC
directive (89/336/EEC).
The FCM 300 complies with:
1)
EN 50081-1 , EN 50082-1.
Residential, commercial and light industrial
environment.
EN 50081-2, EN 50082-2.
Industrial environment.
1) Emission levels stated by EN 50081-1 are only
fulfilled by FCM 300 with class B-1 optional filter.
Furthermore the FCM 300 complies with:
2)
DIN VDE 0160/1990
2) 'Protection against overvoltage 7.3.1. class1'
Product standards
The product standards are stated in EN 61800-3
(IEC 1800-3).
The FCM 300 complies with:
EN 61800-3, unrestricted distribution
EN 61800-3, restricted distribution.
3)
Emission levels stated by EN 61800-3 unrestricted
distribution are only fulfilled by FCM 300 with class
B-1 filter.

General aspects of EMC emissions
For high frequency shielding, shielded cables used
for Profibus, standard bus, control cables and signal
interface must in general be connected to the
enclosure at both ends.
General aspects of EMC immunity
If there are problems with low frequency
interference (ground loops), shielded cable used for
Profibus, standard bus, control cables and signal
interface can be left open at one end.
